[0020] Please see Figures 1 to 5 This utility model discloses a lamp, which includes: The base 1 has an outwardly penetrating receiving groove 13. Each of the two inner sidewalls of the receiving groove 13 has a support part 15 protruding inward. Each of the two outer sidewalls of the base 1 has a connecting hole 14 extending laterally. The connecting hole 14 penetrates the support part 15 and communicates with the receiving groove 13. Each support part 15 has at least one first support post 151 on its upper surface. The first support post 151 has a screw hole 152 that penetrates the first support post 151 and extends vertically. The end of the screw hole 152 near the support part 15 communicates with the connecting hole 14. A light-transmitting cover 2 is placed on one end of the base 1 where a receiving groove 13 is provided; Circuit board 3 is disposed in receiving groove 13. A light-emitting element 31 electrically connected to the circuit board 3 is disposed in the middle of the side of the circuit board 3 facing the light-transmitting cover 2, and the other side is pressed against the first support column 151. Circuit board 3 is provided with multiple through-hole pads 32 that penetrate the circuit board 3 and are electrically connected to the circuit board 3. Multiple connecting wires 4 are sequentially inserted into one connecting hole 14, the receiving groove 13 and another connecting hole 14. Each connecting wire 4 includes a conductive wire 41 and an outer sheath 42 that wraps the conductive wire 41. Multiple conductive screws 501 are provided. Each conductive screw 501 includes a head 51 and a screw portion 52. The screw portion 52 passes through the through-hole pad 32 and is threaded into the screw hole 152. One end of the screw portion 52 away from the head 51 pierces the outer sheath 42 and is electrically connected to the corresponding conductive wire 41. The head 51 is pressed against the upper surface of the through-hole pad 32 so that the multiple conductive wires 41 are electrically connected to the light-emitting element 31 respectively.

[0021] Compared with the prior art, the base 1 of this utility model has two support parts 15 in the receiving groove 13 and a connecting hole 14 through the support parts 15. A first support post 151 is provided on the support part 15. The screw hole 152 of the first support post 151 communicates with the connecting hole 14. The connecting wire 4 passes through the connecting hole 14 and the receiving groove 13. The circuit board 3 is pressed onto the first support post 151 and is provided with a light-emitting element 31 and a through-hole pad 32 electrically connected to it. The screw part 52 of the conductive screw 501 passes through the through-hole pad 32 of the circuit board 3 and is threadedly connected to the screw hole 152 of the first support post 151. The end of the screw part 52 away from the head 51 of the conductive screw 501 pierces the connecting hole 152. The outer sheath 42 of the connector 4 is electrically connected to the conductive wire 41 corresponding to the connecting wire 4. The head 51 of the screw part 52 is pressed onto the through hole pad 32 so that multiple conductive wires 41 are electrically connected to the light-emitting element 31 respectively. This structure allows the circuit board 3 to be installed onto the base 1 using the conductive screw 501. At the same time, the conductive screw 501 realizes the electrical connection between the through hole pad 32 of the circuit board 3 and the conductive wire 41 of the connecting wire 4. This effectively simplifies the assembly steps, improves the assembly efficiency of the lamp, and the structure in which the conductive screw 501 is electrically connected to the through hole pad 32 and the conductive wire 41 respectively can improve the connection stability between the conductive wire 41 and the circuit board 3, which is beneficial to improving the reliability and yield of the lamp.

[0022] See Figures 1 to 5 At least one edge of the head 51 is laser-welded to the upper surface of the circuit board 3, which helps the conductive screw 501 to fit firmly and tightly with the through hole pad 32 on the circuit board 3, further improving the connection stability between the conductive wire 41 and the circuit board 3.

[0023] See Figures 1 to 5 Each of the two outer side walls of the base 1 corresponding to the support part 15 is provided with a limiting part 16. The connecting hole 14 passes through the limiting part 16. The setting of the limiting part 16 can increase the length of the connecting hole 14, which is conducive to the stable insertion of the connecting wire 4 into the connecting hole 14, while restricting the movement of the connecting wire 4 and reducing the risk of the connecting wire 4 breaking.

[0024] See Figures 1 to 5 The bottom wall of the receiving groove 13 is provided with a plurality of second support columns 131 extending vertically. The second support columns 131 abut against the side of the circuit board 3 away from the light-transmitting cover 2. The end face of the second support column 131 that abuts against the circuit board 3 is at the same height as the end face of the first support column 151 that is away from the support part 15, which helps to improve the installation stability of the circuit board 3 in the receiving groove 13.

[0025] Specifically, in this embodiment, four second support columns 131 are provided and are respectively located at diagonal positions near the receiving groove 13. The inner sidewall of the receiving groove 13 is also provided with a plurality of connecting and stabilizing parts 132 protruding outward.

Specifically, in this embodiment, each inner sidewall of the receiving groove 13 is provided with a positioning protrusion 133 and is arranged on the same straight line as the two second support columns 131 in pairs. This is beneficial for the circuit board 3 to be installed into the receiving groove 13 in a specific direction so that the through hole pad 32 is accurately aligned with the screw hole 152 of the corresponding first support column 151.

[0027] See Figures 1 to 5 The base 1 includes a base 11 and a boss 12 extending upward from one end of the base 11 near the light-transmitting cover 2. The receiving groove 13 extends vertically through the boss 12 and into the base 11. The light-transmitting cover 2 includes a flat portion 21 and a side portion 22. The side portion 22 is formed on the side of the flat portion 21 near the base 1 and extends circumferentially along the flat portion 21. The end of the boss 12 away from the base 11 abuts against the flat portion 21. The boss 12 and the side portion 22 are fixedly fused together, which helps to improve the waterproof effect of the lamp.

[0028] Specifically, in this embodiment, the end of the boss portion 12 away from the base portion 11 is fixed to the angle formed by the connection between the flat portion 21 and the side portion 22 by ultrasonic welding. Excess adhesive 25 is provided at the angle formed by the connection between the flat portion 21 and the side portion 22. After ultrasonic welding, it flows out in a fluid form and fills the gap between the outer wall of the boss portion 12 and the inner wall of the side portion 22, so that the boss portion 12 and the side portion 22 are fixedly connected, but it is not limited to this.

[0029] Specifically, in this embodiment, the material of the light-transmitting cover 2 is PC material (polycarbonate), the material of the outer skin 42 is PVC material (polyvinyl chloride), and the material of the base 1 is PVC-ABS alloy material. This facilitates the formation of good airtightness and adhesion after the base 1 and the outer skin 42 are integrally injection molded, and at the same time enables the base 1 to be completely fused with the light-transmitting cover 2 during ultrasonic welding.

[0030] See Figures 1 to 5The lamp also includes multiple connecting screws and a first communication line 401 and a second communication line 402 wrapped with an outer sheath 42.

The circuit board 3 is also provided with a controller, which is provided with an input interface and an output interface. The through-hole pad 32 includes a plurality of first through-hole pads 32 electrically connected to the light-emitting element 31, a second through-hole pad 322 electrically connected to the input interface, and a third through-hole pad 323 electrically connected to the output interface. The first support column 151 is provided with multiple conductive screws 501 or connecting screws 502 respectively. Multiple first through-hole pads 321 are electrically connected to the corresponding conductive wires 41 through conductive screws 501. Second through-hole pads 322 are electrically connected to the first communication line 401 through connecting screws 502. Third through-hole pads 323 are electrically connected to the second communication line 402 through connecting screws 502.

[0031] Specifically, in this embodiment, each support portion 15 is provided with two first support posts 151, and two connecting lines 4 are arranged side by side, namely a positive line 4a and a negative line 4b. Two first through-hole pads 321 are provided corresponding to the positive line 4a and the negative line 4b. The positive line 4a is electrically connected to one of the first through-hole pads 321a through a conductive screw 501 connected to the first support post 151 on one of the support portions 15a. The negative line 4b is electrically connected to the other first through-hole pad 321b through a conductive screw 501 connected to the first support post 151 on the other support portion 15b. The first communication line 401 is electrically connected to the second through-hole pad 322 through a connecting screw 502 connected to the first support post 151 on one of the support portions 15a. The second communication line 402 is electrically connected to the third through-hole pad 323 through a connecting screw 502 connected to the first support post 151 on the other support portion 15b. However, this is not the only embodiment.

[0032] Specifically, in this embodiment, the controller is a control IC. The input interface and output interface of the controller are the DIN interface and DO interface of the control IC, respectively. These interfaces serve as the communication interfaces of the control IC and are used to receive data signals transmitted through the first communication line 401 and to transmit the data signals processed by the control IC to the next level of lamps through the second communication line 402, so as to realize individual control of each lamp.

[0033] Specifically, in this embodiment, the first communication line 401 and the second communication line 402 are arranged side by side with the connecting line 4 and are positioned between the two connecting lines 4. An insulating blocking block 134 is provided on the bottom wall of the receiving groove 13 between the ends of the first communication line 401 and the second communication line 402, but it is not limited to this. The structure and connection method of the connecting screw 502, the first communication line 401 and the second communication line 402 are the same as those of the aforementioned conductive screw 501 and conductive line 41, so they will not be described again.

[0034] See Figures 1 to 5 The light-transmitting cover 2 includes a flat portion 21 and a lens portion 26 that penetrates the middle of the flat portion 21. The light-emitting element 31 is disposed in the middle of the side of the circuit board 3 facing the light-transmitting cover 2, corresponding to the lens portion 26. The end face of the lens portion 26 facing the light-emitting element 31 is concave, and the end face of the lens portion 26 facing outward is convex.

[0035] The light emitted by the light-emitting element 31 is refracted by the concave inner end face of the lens 26 to achieve a mixed optical effect, and then refracted by the convex outer end face of the lens 26 to achieve a dispersed optical effect. By utilizing the above-mentioned secondary optical effect, the direction of the light emitted by the light-emitting element 31 is changed, and a certain beam emission angle is formed, which helps the light emission of the light-transmitting cover 2 to become more uniform.

[0036] See Figures 1 to 5 The flat part 21 facing the light-emitting element 31 has a plurality of pyramidal protrusions 27, which can eliminate some stray light emitted by the light-emitting element 31 to improve the light-emitting effect of the lamp and also blur the display of the internal circuit board 3, thereby achieving the effect of beautifying the lamp.

[0037] See Figures 1 to 5 The light-transmitting cover 2 includes a flat portion 21 and a lens portion 26 that penetrates the middle of the flat portion 21. The side of the flat portion 21 away from the base 1 is provided with an annular concave surface 28 around the lens portion 26. Through the refraction of the annular concave surface 28, the light output of the light-transmitting cover 2 is more uniform, and the annular concave surface 28 can serve as an ID mark to improve the recognizability of the lamp.

[0038] Please see Figures 1 to 5 This utility model discloses an ambient light, which includes: a plurality of lamps arranged at intervals as described above, and connecting lines 4 connecting adjacent lamps to each other.

[0039] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
